This issue is explained by a brief article in the MIT Technology Review, sent by classmate Jorge Cardona. It takes a look at how experts are predicting that blockchain will free data about the grid and reveal more about usage patterns and other critical measures. Here's an excerpt, showing a case of where entrepreneurs are moving in this space:

To unleash the potential of blockchain in the energy sector, Jesse Morris’s team at RMI has joined with Austria-based blockchain startup Grid Singularity to create a new nonprofit called the Energy Web Foundation. Earlier this month, the EWF launched its own blockchain, which Morris says is “purpose-built for the energy sector.” Based on Ethereum, the network will be a test bed for promising use cases. To validate transactions during the test, EWF will rely on 10 major energy companies that have signed on as affiliates.

Classmate Wei Wang sends over the following short article, published in Ars Technica. The piece looks at how attackers have exploited a factorization weakness to steal identities. An excerpt:

A crippling flaw in a widely used code library has fatally undermined the security of millions of encryption keys used in some of the highest-stakes settings, including national identity cards, software- and application-signing, and trusted platform modules protecting government and corporate computers.

The weakness allows attackers to calculate the private portion of any vulnerable key using nothing more than the corresponding public portion. Hackers can then use the private key to impersonate key owners, decrypt sensitive data, sneak malicious code into digitally signed software, and bypass protections that prevent accessing or tampering with stolen PCs. The five-year-old flaw is also troubling because it's located in code that complies with two internationally recognized security certification standards that are binding on many governments, contractors, and companies around the world. The code library was developed by German chipmaker Infineon and has been generating weak keys since 2012 at the latest.

Classmate Nehal Mehta just forwarded on this piece, published by Alexis C. Madrigal in The Atlantic. It looks at how Facebook shaped the outcome of the last election -- and why that effect was so difficult to predict. Key quote:

The information systems that people use to process news have been rerouted through Facebook, and in the process, mostly broken and hidden from view. It wasn’t just liberal bias that kept the media from putting everything together. Much of the hundreds of millions of dollars that was spent during the election cycle came in the form of “dark ads.”

The truth is that while many reporters knew some things that were going on on Facebook, no one knew everything that was going on on Facebook, not even Facebook. And so, during the most significant shift in the technology of politics since the television, the first draft of history is filled with undecipherable whorls and empty pages. Meanwhile, the 2018 midterms loom.

... DeepMind continues to remain independent from its parent company, but its contribution to Google’s product launch is well timed. It reported its first-ever revenues – 40 million pounds ($52 million) in 2016 – from products and services it supplied to other Alphabet companies, according to filings made public on the U.K. business registry Companies House on Monday.

This is just one example of how DeepMind is starting to help Google. Some others that DeepMind has been willing to talk about include supplying algorithms that have helped Google boost the energy efficiency of its data centers by 15 percent, and also improvements to Google’s core ad words product that DeepMind says it cannot detail...

Here's a look at A/B testing, sent over by classmate Rajiv Gupta. The article, published in the Harvard Business Review, looks at the benefits of running experiments on the cheap -- and often. Key quote:

By combining the power of software with the scientific rigor of controlled experiments, your company can create a learning lab. The returns you reap—in cost savings, new revenue, and improved user experience—can be huge. If you want to gain a competitive advantage, your firm should build an experimentation capability and master the science of conducting online tests.

The service began two years ago in India, and Amazon has been slowly marketing it to U.S. merchants in preparation for a national expansion, said the people, who asked not to be identified because the U.S. pilot project is confidential. Amazon is calling the project Seller Flex, one person said. The service began on a trial basis this year in West Coast states with a broader rollout planned in 2018, the people said. Amazon declined to comment.

It's slightly technical, but if someone has any kind of basic programming experience, it can be unbelievably helpful in understanding what's actually going on "under the hood" of bitcoin. It's short but covers everything from hashing to Merkle trees to the actual Blockchain infrastructure. I watched it over the summer and 100% recommend to anyone interested in the topics.

Classmate Varit Sukhum sends along "Managing Our Hub Economy," published in the Harvard Business Review this month. It's a fascinating look at the winner-take-all question which we debated in class, elaborated on in some detail and given a fair trial. Here's a look:

A real opportunity exists for hub firms to truly lead our economy. This will require hubs to fully consider the long-term societal impact of their decisions and to prioritize their ethical responsibilities to the large economic ecosystems that increasingly revolve around them. At the same time, the rest of us—whether in established enterprises or start-ups, in institutions or communities—will need to serve as checks and balances, helping to shape the hub economy by providing critical, informed input and, as needed, pushback.

Classmate Diego Grove sends over this article from the WSJ: "Amazon Takes Over the World." The content should be self-explanatory, but this paragraph, about the MBA experience, may resonate with us.

At New York University’s business school, where I teach, I have for years kept a close watch on which firms are winning the competition for the most talented students. A decade ago, the top recruiter was American Express, with investment banks vying for second position. Now the clear winner is Amazon: 12 students from my most recent class have opted for a life of rain and overrated coffee in the Pacific Northwest.

Classmate Sumit Aggarwal sends over an informative article published in the July-August edition of the Harvard Business Review -- "Find the Platform in Your Product". The title is fairly self-explanatory; the article looks at four ways in which products and services can become multisided platforms. Here's a sample:

Why seek to transform products and services into MSPs in the first place? As one Intuit executive told us, it comes down to “fear and greed.” Greed, of course, refers to the potential for new revenue sources that could speed growth and increase a company’s value. Fear refers to the danger that existing and incoming competitors will steal market share from your product or service. Transforming an offering into a platform might enhance your company’s competitive advantage and raise barriers to entry via network effects and higher switching costs. We’re not suggesting that every company should try to emulate Airbnb, Alibaba, Facebook, or Uber. But many companies would benefit from adding elements of a platform business to their offerings.
